Im trying to pull the members avatar & full name when using type:user in my fieldset so when I pick this in a new blog entry I can then dynamically show this is the author of the post in /blog and /blog/the-entry-is-here

author:
    display: Author
    type: users

I found a post here where Jack mention this:

In 1.7 you'll be able to customize the Member fields just like you can with your content, so you could create any number of File fields, leverage gravatar, etc to do anything you'd like, and pull them out with {{ member:profile }}. How's that sound?

Is there a tag that returns the URL to the member's profile image?
